1. 自建yum仓库，分别为网络源和本地源
配置网络源：
##备份系统自带的yum源文件
[root@centos84 yum.repos.d]# mkdir ~/yum_bak
[root@centos84 yum.repos.d]# mv * ~/yum_bak
##通过wget命令直接下载阿里云yum源
[root@centos84 yum.repos.d]# wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-8.repo
--2021-12-12 06:28:20-- https://mirrors.aliyun.com/repo/Centos-8.repo
Connecting to 172.30.232.251:3128... connected.
Proxy request sent, awaiting response... 200 OK
Length: 2595 (2.5K) [application/octet-stream]
Saving to: ‘/etc/yum.repos.d/CentOS-Base.repo’
/etc/yum.repos.d/CentOS-Base.repo 100%[==================================================================================>] 2.53K --.-KB/s in 0s
2021-12-12 06:28:20 (48.6 MB/s) - ‘/etc/yum.repos.d/CentOS-Base.repo’ saved [2595/2595]
##清理缓存，加载缓存
[root@centos84 yum.repos.d]# yum clean all
[root@centos84 yum.repos.d]# yum makecache
CentOS-8 - Base - mirrors.aliyun.com 12 MB/s | 3.5 MB 00:00
CentOS-8 - Extras - mirrors.aliyun.com 72 kB/s | 10 kB 00:00
CentOS-8 - AppStream - mirrors.aliyun.com 15 MB/s | 8.2 MB 00:00
Metadata cache created.
##列出可用的yum源
[root@centos84 ~]# yum repolist
repo id repo name
AppStream CentOS-8 - AppStream - mirrors.aliyun.com
base CentOS-8 - Base - mirrors.aliyun.com
extras CentOS-8 - Extras - mirrors.aliyun.com
配置本地源
##挂在光盘到/mnt 下
[root@centos84 ~]# mount /dev/sr0 /mnt
mount: /mnt: WARNING: device write-protected, mounted read-only.
[root@centos84 ~]# vi /etc/yum.repos.d/cl8.repo
[BaseOS]
name=BaseOS
baseurl=file:///mnt/BaseOS
enbale=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-centosofficial
[AppStream]
name=AppStream
baseurl=file:///mnt/AppStream
enable=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-centosofficial
[root@centos84 yum.repos.d]# yum clean all
Repository AppStream is listed more than once in the configuration
13 files removed
[root@centos84 yum.repos.d]# yum makecache
Repository AppStream is listed more than once in the configuration
CentOS-8 - Base - mirrors.aliyun.com 3.7 MB/s | 3.5 MB 00:00
CentOS-8 - Extras - mirrors.aliyun.com 39 kB/s | 10 kB 00:00
CentOS-8 - AppStream - mirrors.aliyun.com 20 MB/s | 8.2 MB 00:00
BaseOS 195 MB/s | 2.5 MB 00:00
Metadata cache created.
[root@centos84 yum.repos.d]#
[root@centos84 yum.repos.d]# yum repolist
Repository AppStream is listed more than once in the configuration
repo id repo name
AppStream CentOS-8 - AppStream - mirrors.aliyun.com
BaseOS BaseOS
base CentOS-8 - Base - mirrors.aliyun.com
extras CentOS-8 - Extras - mirrors.aliyun.com
2、编译安装http2.4，实现可以正常访问，并将编译步骤和结果提交
##使用wget 下载Apache httpd 2.4.51 Released源码包
[root@centos84 data]# wget https://dlcdn.apache.org//httpd/httpd-2.4.51.tar.bz2
--2021-12-12 07:00:42-- https://dlcdn.apache.org//httpd/httpd-2.4.51.tar.bz2

##安装编译环境依赖包
yum install gcc make autoconf apr-devel apr-util-devel pcre-devel openssl-devel redhat-rpm-config
##临时关闭selinux
[root@centos84 ~]# setenforce 0
##解压httpd 2.4.51
[root@centos84 data]# tar -jxvf httpd-2.4.51.tar.bz2
httpd-2.4.51/
httpd-2.4.51/acinclude.m4
httpd-2.4.51/README.cmake
httpd-2.4.51/INSTALL

[root@centos84 data]# cd httpd-2.4.51/
##配置
[root@centos84 httpd-2.4.51]# ./configure --prefix=/usr/local/http24 --sysconfdir=/etc/httpd --enable-ssl
checking for chosen layout... Apache
checking for working mkdir -p... yes
checking for grep that handles long lines and -e... /usr/bin/grep
checking for egrep... /usr/bin/grep -E
checking build system type... x86_64-pc-linux-gnu
